I’ve a tremendous knack for catching each illness that goes round. Chilly season? I’m sick. Abdomen bug circulating? Yeah, I’ll get it.
So, when it’s flu season, you higher imagine I’m getting my flu shot. I do know that getting the vaccine doesn’t imply I’m fully protected towards the flu (I imply, who am I kidding with my luck?) however as a well being reporter, I’ve completed sufficient tales on in any other case wholesome individuals who have died from the flu to make me wish to get any safety I can—even when it simply means I’ll get a extra minor case of the sickness.
With that in thoughts, I obtained my flu shot on Wednesday. And by Wednesday evening, I got here down with a fever. I had chills, sweating, and all the opposite enjoyable stuff that comes with a fever. So, I bundled up in mattress, took some acetaminophen, and tried to sleep it off. The following morning, it was again. I took some acetaminophen once more, and went about my day. And, by that night, I had a low-grade fever once more. WTH?
Wait, can the flu shot actually trigger a fever?
Seems, you can get a fever after the flu shot. And, whereas it’s not tremendous widespread, I obtained it. Due to course I did.
It’s necessary to make this clear up entrance: You may’t get the precise flu from the flu vaccine. “What’s within the vaccine is barely a part of the flu virus,” explains William Schaffner, MD, an infectious illness specialist and professor on the Vanderbilt College College of Drugs. “It might probably’t in any manner reconstitute and make you sick.”

How lengthy does this fever often final?
It shouldn’t be greater than a day or two, Dr. Adalja says. “It’s not often one thing that interferes together with your life,” he provides.
What are you able to do when you get a fever after the flu shot?
If it’s bothering you, you may take acetaminophen, Dr. Schaffner says—that ought to deliver the fever down. However, if it’s a minor fever and also you in any other case really feel okay, he says you’re advantageous to simply let it trip.
It’s necessary to level out that your fever with a flu shot ought to be fairly minor, like a level or two above your traditional. (Mine was 100.5 at its worst.) “If it’s actually excessive, extended, otherwise you really feel badly, name your healthcare supplier,” Dr. Schaffner says. “One thing else could be occurring on the identical time.” Translation: In case your fever is excessive and never going away, it’s attainable you already caught the flu—or one other circulating virus—earlier than the vaccine had time to enter full impact (which regularly takes about two weeks).
Certain sufficient, I really feel fairly okay right this moment so, fingers crossed, I’m wholesome once more.
